  • a heating heat exchanger for heating air to be blown into a passenger compartment of the vehicle by using cooling water for cooling the temperature-controlled apparatus as a heating source;

    a first circuit through which the cooling water passes through the temperature-controlled apparatus and the heating heat exchanger;

    a second circuit through which the cooling water passes through the heating heat exchanger while bypassing the temperature-controlled apparatus;

    a switching device for switching a cooling water circuit between the first and second circuits; and

    a control unit for controlling the switching device so as to select the first circuit when a cooling water temperature flowing out of the heating heat exchanger is lower than a cooling water temperature flowing out of the temperature-controlled apparatus.
